mysql连接定义时区

mysql连接错误，有时候存在时区问题，
错误提示：
The server time zone value ‘¥x¥_¼Ð·Ç®É¶¡’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

解决办法：
在jdbc连接的url后面加上serverTimezone=GMT即可解决问题，如果需要使用gmt+8时区，需要写成GMT%2B8

jdbc.url=jdbc:mysql://localhost:3306/o2o?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
